The usage of a galvanometer for providing fine tracking capability for an optical flying head is explored. Some potential R/W and servo problems may be created with such an approach. The source of these problems are analyzed, and a method of how to suppress these problems is proposed. The method we propose can also greatly improve the performance of the galvanometer system.

The rapid prototyping and manufacturing technology (RPM), is an integration of many different disciplines. It is based on an advanced dispersed-accumulated forming principle and originated from 1980s. It generates an entity by first forming a series of layers according to the dispersed section infor...

A new restoration algorithm based on double loops and alternant iterations is proposed to restore the object image effectively from a few frames of turbulence-degraded images. Based on the double loops, the iterative relations for estimating the turbulent point spread function PSF and object image a...

In order to apply compressive sensing in wireless sensor network, inside the nodes cluster classified by the spatial correlation, we propose that a cluster head adopts free space optical communication with space division multiple access, and a sensor node uses a modulating retro-reflector for commun...

This paper introduces some final results of some key technologies in magnetic disk drives. We dicuss the design and experiment of thin film head, magnetic fluid exclusion seal system, head disk interface and the engineering appilcations of these technologies in magnetic disk drives.

Head disk collision models of "coefficient-of-restitution" are widely used in the head disk interface simulation. A new head disk collision model called "critical velocity model" has been developed. Numerical simulation of dynamics of a typical Winchester-type slider is p...
